Title: Bis(phenoxyphenyl)alkanes
IPC: C07C43/263
Filed: 1959-05-12
Abstract: The invention comprises compounds of the formula : <FORM:0853095/IV(b)/1> where R is an alkylene radical containing 5 to 14 carbon atoms. They may be prepared by condensing a dicarboxylic acid chloride containing 5 to 14 carbon atoms with diphenyl ether in the presence of aluminium chloride and reducing the resulting diketone with hydrazine.  The ethers may be used as base oils for lubricants which are exposed to irradiation e.g. by gamma rays. In an example azelaic acid is heated with phosphorus trichloride in diphenyl ether and the mixture is poured into diphenyl ether containing aluminium trichloride.  The crude ketone is recovered as a residue and reduced with hydrazine hydrate in diethylene glycol containing potassium hydroxide to give 1,9-bis-(phenoxyphenyl)-nonane.ALSO:Compounds of the formula: <FORM:0853095/III/1> where R is a C5-C14 alkylene radical, may be used as base oils for lubricants.  The base oils may be blended with oxidation inhibitors, extreme pressure agents, oiliness agents, viscosity index improving agents or grease thickening agents such as silica, sodium stearate, sodium polyethylene phosphonate or sodium N-octadecyl terephthalamate.  The base oils are said to be particularly useful for lubricants exposed to radiation, e.g. by gamma rays.

Abstract: 169,244. Compton, J. H. June 18, 1920. Organ &c. manual actions; sustaining notes.- An expressive-touch action for organs &c. comprises a pianoforte-like hammer, the blow of which directly or through pneumatic means tilts more or less, according to the force of the blow, a contact-carrying member, and so closes a variable number of electric circuits each operating a sound-producing means. As shown in Fig. 1, an L-shaped jack d carried by the key a operates a hammer h which, if the key be struck with sufficient force, tilts more or less a lever pivoted at k, causing a contact l to close one or more circuits m. A stud o on the key restores the lever j to its normal position on release of the key. The lever may however, and while the key is still depressed, be gradually or suddenly raised to diminish the volume of sound, by a bar n operated by a pedal etc.; also the lever j may be retained depressed to sustain a note, by rotating the friction spring q, which is mounted on a rotatable bar instead of on a fixed part as shown. As shown in Fig. 4, the hammer h opens a pallet t admitting more or less air under pressure to a pneumatic w carrying the lever j. An exhaust valve y is simultaneously closed by the key a, and may be retained closed to sustain a.note by raising a rail z. The sound may be increased or decreased by operating adjustable valves 2, 4 by pedals &c., the valve 2 admitting more air from the chamber 6, and the valve 4 allowing air to escape from the pneumatic w. According to the Provisional Specification, a spring may be interposed between the hammer-head and the lever j, Fig. 1, and a friction-cam, provided in lieu of the spring q, may be operated simultaneously by the key.

Abstract: 129,294. Walser, G. July 28, 1917, [Convention date]. Locating subaqueous sounds; subaqueous audible signals.-In apparatus for finding the direction of the source of a subaqueous sound, as in locating submarines, the sound is brought to a focus 7 within the detecting ship 1 by passage through the equivalent of a lens 4 inserted in the skin of the ship. The focus always lies approximately in an horizontal plane 5 when the submarine is at a distance, but its position depends upon the direction of the submarine, its locus being approximately a semicircle. The position of the focus is explored for by a listening horn or the like, and the direction of the sound source deduced therefrom. The member 4 is a plate of spherical form having perforations 14 each with a diaphragm 15 and ring 17 leaving an air space 18 stated to amplify the sound. The spaces between the diaphragms is filled in to preserve the continuity of the surface in contact with the water and so avoid noise due to eddy currents. The diaphragms 15 may be replaced by disks of rubber with ribs to maintain air spaces. The member 4 is inserted in the skin of the ship, with a girdle of cement reinforced with lead, and may have an internal layer of inert material to prevent communication of disturbance from the hull or interior of the ship. The listening horn 26 is pivoted in a fork 27 carried by a frame 25 adapted to rotate about an axis 24 in a support 20 which is pivoted to swing about an axis 22 parallel to the axis of the ship and provided with a weight 21 to maintain the axis 24 vertical. The frame 25 is rotated by a pulley 29 and cable 30 from a control lever, (not shown), so that the horn can be moved to locate the focus by noting in which position the maximum sound. is heard. The horn may be a single cone, or a number of juxtaposed cones with parallel axes, and is always directed towards the centre of the member 4 by cords 31, 32, the latter passing over a pulley 33 and having a counterweight, (not shown).

IPC: H01H35/10
Filed: 1956-06-01
Abstract: 782,889. Speed-responsive switches; switch cases. GENERAL MOTORS CORPORATION. June 1, 1956, No. 16975/56. Class 38 (5). A centrifugal-governor controlled switch device wherein a sleeve mounted coaxially on a rotatable shaft is moved axially by flyweights on the shaft, has first and second resilient members arranged to oppose initial and further motion, respectively, of the sleeve, and at least two switches operable sequentially by the initial and further movements of the sleeve. A shaft 17 adapted to be driven from its squared end 18 or counter-bored end 19, is supported at its former end in a bearing, the outer race 22 of which is received in a bushing 30 secured, together with a housing 76, by screws 36 to the casing. The bushing 30 has stepped portions 34, 35 serving as supports for, respectively, a low-rate spring 70 and a high-rate spring 72, the latter being pre-stressed and bearing against a thrust-washer 78 in the housing 76. The other end of shaft 17 carries a flange 48 on which are three pairs of spaced arms 50, each pair having a bearing pin 54 and ball-race supporting a governor flyweight 52. Surrounding shaft 17 and fitting lightly frictionally over sleeve 33 of bushing 30 is an axially-movable sleeve 60 with a flange 74 engaging the springs 70, 72 at low and high speeds, respectively, and a flange 61 on which is threaded an annular switch operating member 62. The other end of the sleeve 60 supports a ball-bearing, the outer race 65 of which is supported within and by the inwardlyfacing edges of arms 50 so as to rotate with the latter and move axially under the action of projections 69 on the flyweights 52. Two microswitches (only one being shown at S-2, Fig. 1) are mounted on one side of the operating member 62 so as to be operated at low speed by the member 62 moving away from their actuating members, and two further ones S-3, S-4 are mounted on the opposite side for operation at high speeds, all being of identical construction. Thus, a bracket 83 fixed on the base 82 is apertured to pass an operating member 84 which engages and supports one end of a contact arm 85 that straddles the bracket 83. An integral leaf-spring 86 on the contact arm engages the bracket 83 and causes the switch to operate with a snap-action as the upper end of arm 85 moves from one side to the other of the fulcrum. The bases 82 of the switches are adjustable by rotation of their fastening screws 102, and springs 106 take the thrust of the sleeve 60 during operation. In order to prevent undue rotation of sleeve 60 due to friction drag at the bearings, the member 62 thereon carries a pin 110 which engages a torque arm 112 pivotable about a pin 114 in the casing as the sleeve 60 moves axially.

Title: Process for de-inking imprinted paper
IPC: D21C5/02
Filed: 1934-06-08
Abstract: Mechanically disintegrated waste paper is de-inked by cooking with detergents to free the ink particles, an alkaline flocculating agent added if the pH value of the pulp is above 7, or an acid if below 7, the ink being then floated by adding a frothing agent, and the froth separated.  Waste paper from magazines, books, &c. is sorted, dusted, preferably shredded, e.g. in a hammer mill and sent to a broke beater, cooked 3--4 hours in a circulating type cooker using lime, and caustic soda or sodium silicate, or soda ash.  The pulp may then be reduced in consistency, agitated, burnt lime, or magnesium oxide added or alternatively sulphuric acid or alum &c., to precipitate soaps formed in the alkaline cooking; mineral fillers may be dispersed using sodium silicate or soluble starch.  The volume of froth may be reduced by kerosene, a light frothing agent, e.g. cresylic acid, pine oil, or a high boiling point alcohol may also be added, heavier frothing agents, e.g. coal tar oil, pine tar oil may be added during cooking.  Sodium oleate, amyl acetate, butyl alcohol, and potassium ethyl xanthate dissolved in ethyl chlor carbonate may be used as collectors of ink.  The pulp is passed through successive compartments of a flotation machine, and froth from certain compartments returned to the primary pulp feed, remaining froth being washed and used in making board &c.  The pulp may then be filtered, washed, and bleached, and the filtrate used to dilute cooked pulp. In a similar process for newspaper, the pulp, at 3 per cent consistency may be beaten 45--60 mins. at 140--160 DEG  F. in water containing caustic soda and sodium silicate.
